Specification of Letters Patent.

Application filed February 5,1907. s ial N 1 855,889.

To all whom it may concern:

Be it known that I, ALFRED A. ST. J OHN, a citizen;

of the United States of America, residing at New Bediord, in the countyof Bristol and State of Massachusetts, have invented new and usefulImprovements in splice 'Bars and Nut-Locks, of which the following is aspecification.

This invention relates to splicebars and nut locks for railway railsandone of the principal objects of the same is to provide means for firmlyholding the meeting ends of railway rails and to lock the nuts upon thebolts so that they will not turn off said bolts.

Another object of my invention is to provide a rail splice and nut lockof simple construction which will prevent the spreading or creeping ofthe rails and which will hold the bolts and nuts in place for securingthe meeting ends of the rails together.

Still another object of the invention is to provide simple and reliablemeans for holding the nuts on the bolts which will permit ready removalof the nut lock for readjustment of the nuts on the bolts.

The foregoing and other objects may be attained by means of theconstruction illustrated in the accompanying drawing, in which:

Figure l is a side elevation of a rail joint united by my improvedsplice bar and nut lock. Fig. 2 is a sectional view of the same throughthe Web of the rail and through the splice bars. of one of the nutlocks. Fig. 4 isavertical section on the line 4-l, Fig. 1, looking inthe direction indicated by the arrows.

Referring to the accompanying drawings for a more particular descriptionof my invention, the numeral 1 designates the ends of the meeting rails,2. is the web portion thereof, and 3 is the base flange of said rails,the same being of the usual construction. The splice bars, secured atopposite sides of the webs of the rails, consist of a fish plate or bar4 having a thickened portion 5 at the central point which extends by therail joint 6, said bar having the usual bolt holes for the bolts 7. Uponthe opposite side of the web 2 of the rails, the bar 4" is provided withan enlarged or thickened portion 5 having vertical flanges 8. Extendingoutward from Fig. 3 is a perspective view' an undercut groove 9 and nearthe outer end of said bar 4, are lugs 10 provided with verticalapertures or cotter pins 11. The nut locks each consist of a bar orplate 12 having an oblong aperture 13 therein to-fit over the nuts 14and to prevent them from turning therein. A tongue 15 is provided atoneend of said nut lock, said tongue adapted to fit within the groove 9 inthe enlarged portion 5 of the bar 4, and the opposite end of the nutlock having an aperture 16 through which the lug 10 passes.

When the nut locks 12 are secured in place, they are held by means ofthe cotter pins 11 and can be readily removed whenever it is required toreadjust the nuts 14 on the bolts 7.

From the foregoing it will be obvious that my rail splice will firmlyhold together the meeting ends of rails; will not permit the nuts toturn upon the bolts; will permit the ready removal of the nut lock forreadjustment, and does not require any alteration in the present form ofthe rail ends.

Having thus described the invention, what I claim is:

1. A rail splice comprising oppositely disposed .barssecured at thesides of the rail webs and provided withcntral enlargements, one of saidbars having oppositely disposed vertical fianges and undercut grooves,nut locks provided with tongues to fit said grooves-and apertures to fitthe nuts on the bolts, and means for holdingsaid nut lock in place,substantially as described. v

2. A splice for railway rails comprising bars secured at opposite sidesof the webs of theralls, one of said bars having oppositely disposedgrooves, and nut locks provided with tongues to fit said grooves andmeans to prevent the turning of the nuts on the bolts, substantially asde scribed.

3. A splice bar for rails provided with oppositely disposed grooves, incombination with nut locks fitted to said grooves and provided withmeans for preventing turning of the nuts; said splice bar having,outwardly projecting lugs which extend through openings in the nu'tlock, and cotter pins fastened to the lugs for holding the nut lock inplace, substantially as described;
